Willis, 24, will play Sabrina, a bank teller who gets caught in the middle of a botched bank robbery with Max (Masi Oka), who happens to have a soft spot for her. Willis will appear in the same episode as Victoria's Secret supermodel Behati Prinsloo, airing on Dec. 3.

Willis is best known for playing Adriana's ex-girlfriend on the CW soap and for her role in The House Bunny. She most recently guest-starred on Comedy Central's Workaholics.

Hawaii Five-0 airs Mondays at 10/9c on CBS. Are you excited to see Willis on the series? Do you think Max will get the girl?
